Definitions

  • the invention relates to an electronically controlled writing mechanism in a modular design according to the preamble of claim 1.
  • Writing mechanisms for visually and / or machine-readable writing are already known, furthermore writing mechanisms for manually pre-inserted individual forms or for automatically transported continuous paper, writing mechanisms for one or more retrievable paper formats, writing mechanisms for form-independent or form-correct printing as well as writing mechanisms for longitudinal or that Cross-scripting process. It is also already known to control these writing mechanisms electronically. All of these writing mechanisms are designed in a wide variety of combinations. But so far there is no writing mechanism that combines all of the above-mentioned requirements and, particularly when converting from longitudinal to transverse writing, does not require any change in the electronic control program that controls the movement of the writing heads of the writing mechanisms.
  • the task is therefore to create a writing mechanism that is electronically controllable and that is modularly constructed so that it can be used both for visually and / or machine-readable fonts, for manually inserted individual forms or for automatically transported continuous paper, for one or more paper formats that can be called up , for form-independent or form-correct printing as well as for the longitudinal or cross-writing method can be used in the simplest way. Due to the modular design, the writing mechanism with a minimum of parts and construction volume should be universally usable by relocating or omitting modules.
  • a needle head 1 with an ink ribbon cassette 2 is shown, as well as a desk 3.
  • the paper track 4 is located between the needle head 1 and the desk 3. All paper movements take place in this and the diagonally underneath paper path 5.
  • three identical rubber-covered friction rollers 6 are used, which are driven by an electric motor 10 via a common toothed belt 7 by an upstream spur gear transmission consisting of a large gear 9 and pinion 9.
  • the two friction rollers 6 lying in the paper track 4 are arranged as close as possible to the needle head 1 or the ribbon cassette 2.
  • the friction roller 6 lying in the paper track 5 is arranged according to the invention in such a way that, in connection with the wedge piece 11, it does not hinder the linear movement of a writing paper located in the paper track 4.
  • two identical counter-rollers 12 are assigned to the two opposite friction rollers and are rotatably supported in the latter. The two counter rollers are pressed against the two friction rollers 6 by a spring, not shown, acting on the desk 3.
  • a paper located between the roller pairs 6 and 12 can be moved back and forth between the needle head 1 and the desk 3.
  • a magnetic head 13 embedded in the desk 3 is provided for the magnetic writing and reading of a magnetically coated paper.
  • the paper movement can be triggered z. B. by manually inserting a paper through the light barrier 14 from left to right and this starts the electric motor 10 in the direction of rotation, which rotates the friction rollers 6 in the counterclockwise direction, so that the paper detected by these is conveyed from left to right.
  • this paper movement and expedient electronic control of the needle head 1 and / or the magnetic head 13 can be used to serialize a paper. If you only want to write or read magnetically, you can use a plastic card instead of paper.
  • a control cycle is required which is in a fixed relationship to the paper movement in order to ensure a high uniformity of the needle and / or the magnetic writing.
  • the electric motor 10 is a stepper motor, its steps are usually used as a control clock for writing. It is cheaper to use a motor with a pulse disc, but the uniformity suffers due to the tooth play of the reduction gear that is always required.
  • the number of teeth of the large wheel 8 and the diameter of the friction roller 6 are coordinated with one another such that a tooth corresponds to a column of the 7 columns of a needle character or a bit of the magnetic font.
  • the sequence described above can only produce a one-line font because of the rigidly mounted write heads 1 and / or 13. However, if the printheads 1 and / or 13 are made displaceable perpendicular to the plane of the drawing, several lines can be written on the paper. Of practical interest here is only the displacement of the needle head 1.
  • the needle head 1 and the ribbon cassette 2 are mounted on a slide, not shown, which engages with the nut thread in the threaded spindle 16 and is guided on the rod 17.
  • the threaded spindle 16 is driven by the pinion 19 of the electric motor 20 with a large wheel 18.
  • the pinions 9 and 19 and the motors 10 and 20 are expediently the same.
  • the ring gear of the large wheel 18 is scanned by light barrier 21 as previously described for the large wheel 8.
  • An electronic counter (not shown) counts the pulses arising at the light barrier 21 when the threaded spindle 16 rotates and can therefore bring the needle head 1 to a stop at predetermined pulse numbers.
  • the electronic line tab is set with this pulse specification.
  • the line lengths are defined by counting the pulses at light barrier 15 and comparing them with the specified number of pulses (column tabulator). Normally, the motors 10 and 20 always work alternately. With simultaneous specification of pulse number pairs for row and column, plotter operation is also possible.
  • the needle head 5 with the ribbon cassette 2 can also be rotated by 90 ° to the position shown in the drawing on the carriage, not shown.
  • the number of teeth of the large wheel 18 and the pitch of the threaded spindle 1 are matched to one another such that a tooth corresponds to one of the seven columns of a needle character.
  • the threaded spindle 16 then moves the needle head 1 with the ribbon cassette 2 mounted for the transverse printing in the direction of the transverse printing line.
  • the above-mentioned dimensioning ensures that the electronic writing program can remain completely identical in both longitudinal and transverse writing; only the feed lines of the motors 10 and 20 and the feed lines of the light barriers 15 and 21 have to be interchanged.
  • the cross-writing method (line direction transverse to the paper transport direction) is often preferred to the longitudinal writing method because the paper movement is less (but the head movement is larger) and because journaling is only possible crosswise.
  • a machine paper feed (paper dispenser) is integrated into the previously described writing mechanism, which consists of rocker 22 with counter roller 23 and actuating magnet 24, as well as the parts of wedge piece 11 already described at the beginning and the friction roller arranged on the right, which has not been used in the previously described writing processes 6.
  • the paper 25 held in roll or fan-shaped form runs from the right into the paper track 5 and is pressed there against the wedge piece 11 in a known manner by the brake bolt 26 seated in the rocker 22. In this rocker position, the friction roller 6 projecting into the paper track 5 does not yet come into contact with the paper 25.
  • the rocker 22 tilts in the counterclockwise direction such that the counter roller 23 presses the paper 25 against the friction roller 6 and at the same time the brake pad 26 lifts off the wedge piece 11 and thus releases the paper 25.
  • the motor 10 starts at the same time so that the friction rollers 6 rotate clockwise, then the paper 25 runs from the paper track 5 into the paper track 4 and can, as already explained, in needle letters and / or magnetic letters, one line or multiple lines, in longitudinal writing. or be described in cross-writing.
  • several paper dispensers can be arranged side by side, which cooperate with the same friction roller 6 and the same wedge piece 11 and the like paper path 4.5 5.
  • the special paper supply is selected by actuating the special actuating magnet 24.
  • the paper supply is available as a form, there are tabs despite precisely programmed rows and columns Error tolerance tolerances inevitable, which can result from paper stretching, slippage and friction roller wear.
  • the paper must be provided with control holes that are always in the same position for form printing.
  • a continuous light rod 27 is mounted in the wedge piece 11, which throws a narrow strip of light into the paper track 5.
  • a photo transistor 28 which is covered by the paper 25, unless a control hole runs through the paper 25. Then the phototransistor 28 emits a signal which is used for the form-correct synchronization of the column tabs in the case of the longitudinal writing or the line tabs in the case of the cross-writing.
  • a cutting tab must be set in the control program in the form of the number of cycles that brings the edge to be cut in the paper 25 transported out to the left to the cutting edge 29 of the rotary knife 30 and the counter knife 31.
  • the motor 10 is stopped and the rotary knife 30 is moved via the rocker arm 32, crank rod 33, Kurbe134 and knife motor 35.
  • the motor 10 is started in reverse, so that the paper 25 runs back to the right and stops after the motor 10 has reached a constant number of cycles. This number of cycles results from the length in the paper tracks 4 and 5 between the cutting edge 29 and a point about 5 millimeters to the left of the brake pad 26.
  • the advantages of the writing mechanism according to the invention are that it meets all the requirements mentioned at the outset and that it can be used universally by moving or omitting individual modular assemblies with a minimum of parts and construction volume.
